Pelagia Testnet
Learn how to connect to and deploy on Reef Pelagia, the next-generation Reef Chain testnet.
Testnet tokens have no real value and state may be reset on upgrades.
What is Pelagia?
Reef Pelagia is the new Reef Chain testnet representing the core blockchain upgrade currently in progress. It is intended as a stress-test and feedback environment for developers before changes are promoted to mainnet.
Pelagia was first opened to hackathon participants at Web3Conf Enugu 2025 (September 20–27, 2025), where multiple projects successfully deployed to it during the event.

Deploy Smart Contracts
Since we are using this opportunity to upgrade Reef’s Substrate/Polkadot libraries and implement pallet-revive,
you can begin here to find docs and tools to deploy:
Next steps
Explore the tools and frameworks available for building and testing smart contracts on the Reef network.
These environments streamline the development process, from writing and compiling to testing and deploying smart contracts.
The guides in this section will help you evaluate each tool’s strengths, making it easier to choose the best fit for your project based on complexity, team expertise, and specific requirements.
What to Consider
Consider the following when evaluating development environments for your workflow:
| Development Environment | Web-Based | Installation Required | Best For | Compilation & Deployment | Testing & Debugging | Extensibility |
| ----------------------- | --------- | ---------------------------- | ------------------------------------------ | -------------------------- | ----------------------------------- | ---------------------- |
| Remix | Yes | No | Beginners, quick prototyping | Built-in UI & compiler | Basic tools | Limited plugin support |
| Hardhat | No | Yes (via package manager) | Advanced development, scripting, automation| Script-based | Mocha, Chai, mainnet forking | Highly customizable |
